Here's a color schema depicting the approximate territory each faction controls at the start of a game of ES:I. Something to take note of is that Teal controls the Daedric Realm of Coldharbour all on his own, and starts with very little territory on Tamriel itself. Teal may teleport his forces from Coldharbour to Dark Anchor Dolmens under the control of his team, meaning that he is reliant on Red and Brown to keep control of important Dolmens, otherwise they will be at a disadvantage. Brown, while particularily strong in southwestern Skyrim and northern Cyrodiil, also controls pockets of cultists around the map, but these are not marked here. Another important note is that while some players own more land area at the start, these factions will also have thinner, more scattered armies. For example, while the Dunmer of Morrowind and the Nords of Skyrim control vast areas of land, the amount of soldiers there is sparse. On the other hand, the Aldmeri Dominion team controls few cities and little territory, yet their armies are heavily concentrated in the south, and may break through by sheer numbers.
